QTextBrowser and Scrolling area
Message 1 in thread
Good afternoon.
I would like to know if there is a way, when I call setHtml(QString s) on a
QTextBrowser, to avoid that the scrollbars scroll to the beginning.
Moreover, is there a simple way to make them always scroll to the end
(text browser is read-only)
Thanks a lot
Giacomo.

Use QTextEdit::ensureCursorVisible after you've moved the cursor to
the end of the document.

Thanks.
And to avoid any scrolling when setHtml() is called?

int vPos = doc->verticalScrollBar()->value();
int hPos = doc->horizontalScrollBar()->value();
doc->setHTML( content );
gui_->log_->verticalScrollBar()->setValue( vPos );
gui_->log_->horizontalScrollBar()->setValue( hPos );
Does that work?

Ack! Cut-and-paste error:
int vPos = doc->verticalScrollBar()->value();
int hPos = doc->horizontalScrollBar()->value();
doc->setHTML( content );
doc->verticalScrollBar()->setValue( vPos );
doc->horizontalScrollBar()->setValue( hPos );
